In ancient times, due to the limitation of the level of science and technology, people can not easily control the indoor temperature, and thus suffering from severe cold and heat, with the changes of the times, the development of science and technology, now people can easily achieve the indoor temperature control, help people to achieve the indoor temperature control equipment is the fan coil.
According to the majority of users, the fan coil has a good cooling and heating effect and can create a comfortable indoor environment. However, the only drawback is that it will make a relatively large noise when working. What is the cause of this problem and what measures can users take to reduce noise.
It is understood that due to the limitations of the current technical level, the actual noise levels of various fan coils at home and abroad are generally high, and domestic fan coils have reached the international level in terms of noise treatment.
In this case, the main reasons for the excessive noise of the fan coil are as follows:.
Due to the different installation positions and configuration methods of the fan coil in the room, the noise level of the fan coil varies from high to low. According to the tests conducted by relevant units on the fan coil at different installation locations, when the fan coil is turned on at high speed, the upper limit of the noise field is nc-45 and the lower limit is nc-35. When the fan coil is turned on at low speed, the upper limit is nc-40 and the lower limit is nc-25.
In view of the above causes of excessive noise in indoor fan coils, it is recommended that users adopt the following countermeasures:.
When selecting fan coil units, users should consider the installation position of fan coil units according to the level of quietness requirements of the room. When installing bedrooms with high quietness requirements, silencing treatment can be done in the air duct between the outlet of fan coil units and the air outlet of the room. Column fan coil units should be installed far away from beds and tables, and silencing devices can also be added to the air outlet of the air outlet. The requirements for quietness are general, horizontal or vertical fan coils with medium noise level can be selected.
Excessive noise will affect the user's mood, and even harm the health of the fan coil. It provides customers with countermeasures for the problem of excessive noise of the fan coil, hoping to reduce the noise to the majority of users, so that users can enjoy the comfortable indoor environment and enjoy the convenience brought by high-tech achievements.
The fan coil body is compact in structure, sturdy and durable. It usually adopts high-quality galvanized sheet casing. The condensate water pan is integrally formed by molding process. There are no welds and welding spots. The thermal insulation material conforming to the fire prevention code is integrally connected to the water pan. The installation of drain pipe and circuit is simple. The left and right connecting pipes and return air modes can be changed at any time to match the site conditions. The unit can be installed in any space. The fan coil pipe expansion process, the close contact between the copper tube and aluminum foil of the heat exchanger is increased, the heat transfer performance is good, the reasonable design of the fan and air flow structure, and the high-quality sound-absorbing and thermal insulation materials make the noise of the unit lower than the national standard 1-3dB(A). The energy consumption of the fan coil is low: the fan and the heat exchanger are reasonably matched, and the air volume can be adjusted in three gears, so that the fan coil can save electricity.
The fan coil mainly relies on the forced action of the fan to heat the air when passing through the surface of the heater, thus strengthening the convective heat transfer between the radiator and the air, and can quickly heat the air in the room. The fan coil is the terminal device of the air conditioning system. Its working principle is that the air in the room where the unit is continuously recirculated, so that the air is cooled (heated) after passing through the cold water (hot water) coil, in order to keep the room temperature constant, usually, the fresh air is sent into the room after being processed by the fresh air unit to meet the needs of the fresh air volume in the air-conditioned room.
Because this kind of heating method is only based on convection heat exchange, and the indoor can not reach a better comfort level, so it is only suitable for places where people stay for a short time, such as: offices and hotels, hospitals, restaurants, factories, hospitals, exhibition halls, shopping malls and office buildings and other multi-room or large-space industrial and civil buildings air-conditioning occasions, due to the increase of fans, increase the cost and operating costs, equipment maintenance and management is also more complex.
